The asphalt plants or asphalt mixing plant is one plant that is used for mixing the dry warm aggregate, padding and asphalt for homogeneous mixture at the required temperature. It is widely used for construction of highways, city roads and parking lots. An asphalt plant is a plant used for the manufacture of asphalt, macadam and other forms of ...
Asphalt batch mix plant A machine laying asphalt concrete, fed from a dump truck. Asphalt concrete (commonly called asphalt, [1] blacktop, or pavement in North America, and tarmac or bitumen macadam in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams.

There are about 4,000 asphalt concrete mixing plants in the US, and a similar number in Europe. [85] Asphalt concrete is usually placed on top in a road. Asphalt concrete pavement mixes are typically composed of 5% bitumen (known as asphalt cement in the US) and 95% aggregates (stone, sand, and gravel).
The Municipal Asphalt Plant is a former asphalt plant at York Avenue and 91st Street on the Upper East Side of Manhattan in New York City, housing the Asphalt Green recreation center. The asphalt plant was completed in 1944 to designs by Ely Jacques Kahn and Robert Allan Jacobs .
Cold mix asphalt is often used on lower-volume rural roads, where hot mix asphalt would cool too much on the long trip from the asphalt plant to the construction site. [18] An asphalt concrete surface will generally be constructed for high-volume primary highways having an average annual daily traffic load greater than 1,200 vehicles per day. [19]
Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. Concrete is the second-most-used substance in the world after water, [ 1] and is the most widely used building material. [ 2] Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined.
Stone mastic asphalt ( SMA ), also called stone-matrix asphalt, was developed in Germany in the 1960s with the first SMA pavements being placed in 1968 near Kiel. [ 1] It provides a deformation-resistant, durable surfacing material, suitable for heavily trafficked roads. SMA has found use in Europe, Australia, the United States, and Canada as a ...
